Read the Amplifier class notes.

For the amplifier circuit shown, R_S = 22 kΩ, and R_L = 680 Ω.

For amp 1: R_i1 = 82 kΩ, A₁= 5, R_o1 = 5.6 kΩ.

For amp 2: R_i2 = 3.3 kΩ, A₂= 20, R_o2 = 1.5 kΩ.

For amp 3: R_i3 = 3.9 kΩ, A₃= 5, R_o3 = 270 Ω.

If the amplitude of the input signal is v_i = 0.4 V, find the amplitude of the amplified output singnal, v_o.
